How to choose qualified cement
1. cement production date
Date of cement production. Buying cement depends first on its production date. It is valid for 30 days. If the product exceeds this period, the quality will decline. Moreover, the longer the cement is stored, the worse the product quality. Usually, high-quality cement can be solidified in more than 6 hours, and the cement that cannot be solidified in more than 12 hours is of poor quality.
2. Cement paper bag packaging
No matter what kind of product packaging you buy, it also reflects the quality of the product. Therefore, when you buy cement, you should also check whether the paper bag packaging of cement is intact, and whether the logo on the paper bag has information such as factory name, cement name, registered trademark, year, month, day, variety packaging quantity, etc.
3. Cement color
It is important to see the color of cement surface, and observe whether the color is dark gray or dark green. If the cement is yellow and white, yellow means that the clinker is raw, and white means that there is too much slag, so the cement color is not good.
4. Cement fineness
The last one is to look at the fineness of cement, that is, twist cement powder with your fingers, and it feels a little fine, with sand and powder, indicating that the fineness of cement is normal.
